android - Android Studio:找不到com.android.support:support-v4:22.2.1

Question

我的依赖项包括以下内容:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.github.satyan:sugar:1.3.1'
    compile 'com.android.support:support-v13:+'
}

并且项目得到很好的编译，但是当我添加以下内容时:

compile 'com.mohamadamin:persianmaterialdatetimepicker:1.2.1'

我收到此错误消息:

Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugCompile'.
   > Could not find com.android.support:support-v4:22.2.1.

我进行了很多搜索，但似乎无济于事。我该如何解决这个问题？

Answer 1

如果您拥有appcompat-v7:22.1.1，则意味着您应该拥有support-v4:22.1.1。您尝试使用的库正在请求support-v4:22.2.1，这是较新的。

确保您的Android存储库在SDK Manager中是最新的。通常，拥有较旧的 Artifact 而不是较新的 Artifact 意味着您最近没有更新Android Repository。
